To determine the slant height, you will use what you know about surface area of a pyramid.
The surface area of a square Peerman consists of one square, and four congruent triangles.
We know the length of one side on the square base is 18 inches.
The area of the base then would be 324 in.².
Subtract this from the total surface area.
864-324 = 540 in.²
Divide 540 in.² by 4 because there are four congruent triangles.
540/4= 135 in.²
Each triangle is 135 in.². Now use the formula for area of a triangle to solve for the missing slant height.
A = 1/2 x b x h
135 = 1/2 x 18 x h
135 = 9h
h = 15 inches.
The slant height is 15 inches.
The answer is a space contains at
least four points that do not lie in a same plane or not all in the same plane. An axiom is a statement or
proposition that is observed as being established, accepted, or self-evidently
true. In other words, it is any statement or mathematical statement that functions
as a starting point from which other statements are logically derived. So this
can be found on postulate 1 that states “a line containing at least two points;
a plane contains at least three points not all in one line; and a space
contains at least four points not all in the one plane.”
